Sapphos Environmental, Inc. prepared the Resource Management Plan for the 2,783-acre Ahmanson Ranch property in eastern Ventura County, which was acquired by the State of California and is being held in trust by the Santa Monica Mountains Conservancy. The Ahmanson Ranch property eventually will become a part of the Santa Monica Mountains National Recreation Area. The Resource Management Plan provides guidelines for managing state-designated sensitive habitats, including extensive native grasslands, oak woodlands, and wetlands; two special status species, the California red-legged frog (a federally threatened species) and the San Fernando Valley spine flower (a federal- and state-candidate species); wildfire fuel modification; and archaeological and paleontological resources.

Sapphos Environmental, Inc. worked in collaboration with the U.S. Fish and Wildlife Service, the California Department of Fish and Game, and the Los Angeles Zoo to develop conservation and recovery strategies for the California red-legged frog and the San Fernando Valley spine flower. Sapphos Environmental, Inc. obtained a Section 10(a) permit to facilitate captive breeding of the California red-legged frog. In addition, a permit was obtained from the California Department of Fish and Game to collect seed from the San Fernando Valley spine flower. The seed was used successfully to propagate plants in the laboratory and in situ on the Ahmanson Ranch property.

Development of the Resource Management Plan involved extensive coordination with regulatory agencies, including U.S. Army Corps of Engineers, U.S. Fish and Wildlife Service, National Park Service, California Department of Fish and Game, Regional Water Quality Control Board, County of Ventura, Las Virgenes Creek Watershed planning team, and the Las Virgenes Institute.
